MULTI-FIBER TYPE OPTICAL CABLE COUPLER AND PROCESS FOR PRODUCTION THEREOF

摘要

When a multi-fiber type optical cable coupler obtained from a tape core wire (1) is fixed to a reinforcement case (3), a glass portion (2b) as a non-extension portion outside a fusing extension portion (2c) of the coupler and a protective cladding layer (2a) at the back of the glass portion (2b) are fixed by an adhesive layer (4). A collective coating resin layer (1a) of the tape core wire (1) is not fixed to the reinforcement case (3). When it is fixed, it is fixed to the reinforcement case (3) by a soft adhesive layer (5) different from the adhesive layer (4) described above. A resin having a viscosity of 50 to 200 P or a UV-curing and thermosetting resin is suitable as the resin of the adhesive layer (4).
